Embodiment
Fig. 1 illustrates device 1, and it avoids the magnetic energy by source 3 radiation for the protection of the space 2 adjacent with magnetic source 3.
This device is essential in a lot of fields, so that protection people avoids the magnetic energy by radiation of equipment, magnetic energy is useful for described equipment in addition.
Especially, vehicle 22 shown in Figure 4 comprises wheel 24,25 and for driving the machine 23 of all or some these wheels.Machine 23 is controlled by power supply 13.
When machine 23 is Thermal Motor, the power supply 13 of the first kind for example produces igniting sequence in the situation that of gasoline combustion, and/or the in the situation that of gasoline or diesel combustion, produces the sequence for controlling injector.
When machine 23 is motor, the special generation current of power supply 13 of Second Type, according to the plus or minus direction of electric current, described electric current makes machine 23 as engine or generator operation.Then power supply 13 is grouped together battery and power electronic equipment.
Other element in motor vehicles or in other environment can form static father 3 or radiation field equally.
Other space may need protection to avoid personnel to be exposed to magnetic field, for example unrestriced by means of pure illustrative, adjacent with transformer station or the heavy current distribution line in factory.
Usually, the device 1 of Fig. 1 comprises ferromagnetic material sheet 4, and this sheet stretches between space 2 and magnetic source 3.
Attempt realizing optimum possible performance, for reducing the magnetic field adjacent with source with optimal cost, kept the demand of restraint device 1 weight simultaneously.In fact, light weight (particularly in motor vehicles) in many engineering results is basic important need.
Should be noted that Ampere's law has illustrated in known manner in the circulation of the magnetic field B of closed curve and the ratio through the surperficial electric current being limited by this closed curve and contacted in the state of stable or almost stable.
Be known that in a vacuum, scale factor equals 4 Π x10
-7the permeability of vacuum μ of Tm/A
0.The magnetic permeability μ of the medium different from vacuum is by by permeability of vacuum and the scale factor μ of relative permeability that is called characterized medium
rmultiply each other and obtain.
In dynamical state, ampere-Maxwell's law illustrated magnetic field and relate to the electric field time change electric current between relation.
Above-mentioned knowledge is for changing the electric current in source 3, to obtain in the frequency of describing the frequency spectrum changing to several MHz from several Hz the magnetic field being produced by magnetic source.
By being recorded in the build-up radiation magnetic energy in the frequency range that is less than given threshold value, for the threshold value between 10Hz and 100Hz, observe the remarkable increase in build-up radiation energy, and then for the threshold value between 100Hz and 1000Hz, observe further and increase.Accumulation magnetic energy is faint increase then, is tending towards asymptotic value for the threshold value between 1000Hz and 10MHz simultaneously.
In view of this observation, attempted inking device 1 in case as much as possible from 10Hz to 1kHz(even up to 10kHz) change frequency range in by field decay.
In these frequency bands, be suitable for being most preferably ferromagnetic material for the material of magnetic field formation barrier.
If the known paramagnetism electric conducting material such as aluminium allows magnetic field suitably to decay at high frequency treatment, they are unsuitable for for magnetic field, forming barrier at low frequency place.Although the aluminium sheet with finite size and 1mm thickness has allowed the decay of realization-58dB in the frequency band between 100kHz and 2MHz, but this same plate has only allowed be only limited to-2dB of decay for the frequency that is less than 100Hz, and for the frequency that approaches 400Hz only-7dB.
For ferromagnetic material, seek to occupy the relative permeability μ with high value
rferromagnetic material, in other words, be greater than 100000 to realize good result at low frequency place.
For example this is the nickel of 77-80% substantially and the Alperm of 15% iron composition, wherein copper and/or molybdenum composition remainder substantially.The feature of this material is: the relative permeability in 150000 regions, and it promotes departing from of magnetic field line at low frequency place; And the Curie temperature of about 420 ℃, this is very suitable for thermal environment, because may run into the situation adjacent with engine.
By increasing frequency from 10Hz to 10MHz, first measure the magnetic field between source 3 and device 1, and the fixed point measurement on device 1 either side subsequently exceeds the magnetic field in the space 2 of device 1, to can compare and measure value.For each frequency, the ratio between two measured values provides the decay being brought by barrier device.
Alperm sheet allows to realize the decay of substantial constant, it alternately changes a little approximately-7.5dB in the frequency range from 10Hz to 1000Hz, in the frequency range from 1kHz to 4kHz, be reduced to substantially-17dB, then after exceeding 4kHz and being in, near a value, keep substantial constant.These values also depend on the size of sheet.
In order to increase fade performance, use the Fe-based amorphous matter alloy with non-directional nanocrystalline structure as the possibility of ferromagnetic material after deliberation.For distinguishing such and Alperm class, the material that belongs to this type of is by being abbreviated as the ferromagnetic nanocrystal noncrystalline of FMNA() the remainder of description in specify.
In this class material, NANOPERM
tMit is the ferrous alloy that comprises silicon and formed by a small amount of copper, niobium and boron.It allows to realize 200000 magnetic permeability, depends on its supplier.Supplier's specification indication is less than the magnetostriction coefficient of 0.5ppm.
In this class material, FINEMET
tMbe ferrous alloy, this ferrous alloy comprises one group of chemical element that comprises silicon equally.The relative permeability μ of supplier's specification indication approximate 70000
rwith approximate 10
-7low-down magnetostriction coefficient.This low magnetostriction coefficient is conducive to attempt noise that reduce to be produced by magnetic field, that vibrate in the frequency band that can hear.
FINEMET
tMsheet is the ferromagnetic material sheet being covered by electrical insulation material layer on its each.
Every one deck of electrical insulating material comprises that thickness is the PET(PETG of 25 μ m) film, wherein film is connected to ferromagnetic material sheet by the bonding material layer with 25 μ m thickness.Because the thickness of ferromagnetic material itself is 18 μ m, therefore obtain the FMNA material piece with 0.12mm.
By repeating the experiment identical with adopting Alperm, the FMNA material piece with 0.12mm has allowed to realize the decay of substantial constant, it alternately changes a little approximately-2dB in the frequency range from 10Hz to 1000Hz, in the scope from 1kHz to 5kHz, advance to substantially-14dB, then after exceeding 5kHz and being in, near a value, keep substantial constant.
There are two stacking decay that allowed to realize substantial constant of the FMNA material of 0.12mm thickness, it alternately changes a little approximately-4dB in the frequency range from 10Hz to 1000Hz, in the scope from 1kHz to 3kHz, advance to substantially-15dB, then after exceeding 3kHz and being in, near a value, keep substantial constant.Should be noted that sheet quantity double at low frequency place, bring pure proportional improvement in performance, and almost do not improve at high frequency treatment.
There is the stacking decay that has allowed to realize substantial constant of three FMNA material piece of 0.12mm thickness, it alternately changes a little approximately-6dB in the frequency range from 10Hz to 1000Hz, in the scope from 1kHz to 2kHz, reach substantially-10dB, then after exceeding 2kHz and being in, near a value, keep substantial constant.Should be noted that three times of sheet quantity bring small size improvement in performance at low frequency place, and worsen at high frequency treatment.
For overcoming in the performance of high frequency treatment, worsen, aluminium flake stretches between source and ferromagnetic material sheet.The sheet of conductive material of eliminating or at least greatly reduce magnetic field radio-frequency component, mainly by the low-frequency component that only sends magnetic field to it, alleviates the barrier function that will be realized by ferromagnetic material.
By extending in source 3 and thering is the aluminium flake with 1mm thickness between the FMNA material piece of 0.12mm thickness, realized decay, it from-advance to-17dB of 3dB, then keeps substantial constant exceeding be in approximately-25dB of 2kHz in the frequency range from 10Hz to 1000Hz.Should be noted that stretching paramagnetism sheet of conductive material brings improvement in performance at high frequency treatment, and become remarkable at the relative low frequency of the 700Hz from realization-15dB decay.
By extending in source 3 and thering is the aluminium flake between two FMNA material piece of 0.12mm thickness with 1mm thickness, realized decay, it from-advance to-18dB of 4dB, then keeps substantial constant exceeding be in approximately-30dB of 3kHz in the frequency range from 10Hz to 1000Hz.Should be noted that compared with the aluminium flake extending between source 3 and single FMNA material piece, the paramagnetism sheet of conductive material extending between source 3 and two ferromagnetic material sheets is brought small size improvement in performance.
In surprising mode, above the face of FMNA material piece with 0.12mm thickness relative with the face of facing source 3, stretching, extension has the aluminium flake of 1mm thickness and has realized decay, its in the frequency range from 100Hz to 1000Hz from-advance to-22dB of 3dB, then exceed 2kHz place approximately-25dB keeps substantial constant.Should be noted that after the ferromagnetic material sheet relevant with source 3, stretching paramagnetism sheet of conductive material brings improvement in performance at low frequency place, it is obviously greater than the improvement that adopts above two previous experiments to obtain.This configuration allows to adopt single FMNA material piece to realize the better performance of performance that adopts two FMNA material piece to obtain than in relative configuration.In addition, because all parameters are equal, so decay increases when (multiple) aluminium flake thickness increases.
This result is preferably unconspicuous, because in a rear configuration, before the propagation towards ferromagnetic material sheet, ferromagnetic material sheet is submitted to whole magnetic field and should trends towards promoting the saturated phenomenon in ferromagnetic material.
This structure is favourable, because it improves performance, cuts down the cost that half is affected by the structure of FMNA material piece simultaneously, and the latter is relatively very high.
By above two the FMNA material piece with 0.12mm thickness relative with source 3, stretching, extension has the aluminium flake of 1mm thickness and has realized decay, its in the frequency range from 10Hz to 1000Hz from-advance to-22dB of 8dB, then exceed 3kHz place approximately-30dB keeps substantial constant.Should be noted that with stretch aluminium flake above single FMNA material piece compared with, above two the ferromagnetic material sheets relative with source 3, stretch paramagnetism sheet of conductive material and bring hardly any improvement in performance.
Above face by the single ferromagnetic material sheet relative with the face of facing magnetic source, stretch a non-ferromagnetic sheet of conductive material, according to validity and cost, therefore obtain the first optimal effectiveness.
In the device of Fig. 1, diamagnetism or paramagnetism sheet of conductive material 5 advantageously stretch between sheet 4 and the space 2 that will protect.
But, attempted finding further to improve the alternate manner of performance.
Equally in surprising mode, by above other face of single FMNA material piece with 0.12mm thickness, stretching, extension has the second aluminium flake of 1mm thickness and has realized decay, its in the frequency range from 100Hz to 600Hz from-advance to-35dB of 5dB, then more little by little at reach-37dB of 1000Hz place, then exceed 1kHz place approximately-37dB keeps substantial constant.Should note, on the either side of the ferromagnetic material sheet relevant with source 3, stretch paramagnetism sheet of conductive material and bring improvement in performance at low frequency place, this is obviously greater than those summations that adopt the previous experiment of using non-ferromagnetic sheet of conductive material to realize, wherein sheet and the combination of ferromagnetic material sheet.This configuration allows the better performance of the performance that previous experiment was realized realizing with single FMNA material piece than adopting.Equally in this case, should be noted that, along with all parameters equate in addition, decay increases when aluminium flake thickness increases.
This result is preferentially unconspicuous, because in the latter configuration, the technique effect for magnetic field barrier bringing as the combination of passing through sheet of being seen is much larger than the effect summation of bringing by each (summation of even paired sheet combination).
Certainly, add extra non-ferromagnetic sheet metal and can have cost and weight impact, be used in particular for mobile purposes, the latter is important selection factor.Depend on the tolerable intensity of radiation magnetic energy, single non-ferromagnetic sheet of conductive material may be acceptable, and this sheet is stacked on the face of the ferromagnetic material sheet in space one side that will protect.
But, when magnetic field intensity proves the increase a little of cost and weight, consider and some other Metal Phase ratios, aluminium is relatively light metal, and the cost that cost is significantly less than the material piece combining with strong magnetic permeability, high magnetic saturation threshold level and low magnetostriction is (as FINEMET
tMsituation), the obvious tendency that the present invention instruction is used for two non-ferromagnetic metals (more specifically paramagnetic metal) sheet.
Therefore, the device 1 of Fig. 1 comprises the second diamagnetism or paramagnetism sheet of conductive material 6, and wherein sheet stretches between ferromagnetic material sheet 4 and magnetic source 3.
Presented from above-mentioned disclosed test, this test increases the quantity of ferromagnetic material sheet and brings the small gain in performance.
But, by insert several ferromagnetic material sheets between two nonferromagnetic material sheets, carry out test.
Between two aluminium flakes with 1mm thickness, there are two FINEMET of 0.12mm thickness
tMthe stacking of material piece allowed realization to decay, its adopt from for 50Hz frequency-7dB to height to for 350Hz frequency-sharp gradient of 35dB and advancing, but again adopt the high slight gradient to substantially-37dB at 1kHz place and advance, then exceed 5kHz place about-36dB keeps substantial constant.Different from test above, should be noted that sheet quantity double at low frequency place, bring remarkable improvement in performance, and high frequency treatment tend to a little reversion.
Between two aluminium flakes with 1mm thickness, there are three FINEMET of 0.12mm thickness
tMsheet stacking allowed to realize decay, it is same adopt from for 50Hz frequency-10dB to height to for 400Hz frequency-the almost identical sharp gradient of 35dB and advancing, then exceed 1kHz place about-33dB keeps substantial constant.Should be noted that sheet quantity double at low frequency place, bring remarkable improvement in performance, and high frequency treatment tend to a little reversion.
Optimal solution is revealed as the scheme of Fig. 2, wherein installs 11 and comprises the second ferromagnetic material sheet 7, and this sheet stretches between the first ferromagnetic material sheet 4 and the first sheet of conductive material 5.
Fig. 3 allows a kind of method of manufacturing installation, and this device is avoided the magnetic energy by the source radiation that will describe for the protection of the space adjacent with magnetic source.
First step is the first diamagnetism or paramagnetism sheet of conductive material 15 to be shaped.Shaping is included under pressure and will for example has the behavior of sheet metal (comprising aluminium) distortion of 1mm thickness, or the behavior of molded panel when material is difficult to punching press.In order to stretch the sheet 15 with the first surface relative with the space that will protect, lug 8,10 is cut, folding and/or processing, wherein does and portals, and it will allow sheet to fix near this space that will protect.Not perforated tongue 18 can be formed equally, for the fixing means by pegging or for any other function.
Second step be with the similar mode of mode of first step, the second diamagnetism or paramagnetism sheet of conductive material 16 are shaped.In order to stretch the sheet 16 with the first surface relative with magnetic source, lug 9,20 is cut, folding and/or processing, and it can be stacking near lug 8,10, and wherein do and portal, and it will allow sheet 16 fixing together with sheet 15.Not perforated tongue 19 can be shaped to equally for engaging tongue 18.
Third step is, above second of first sheet of conductive material 15 relative with the first surface of first 15, stretches one or more ferromagnetic material sheets, preferably two sheets 14,17.The surface area of the every a slice in sheet 14,17 is preferably less than the surface area of the every a slice in sheet of conductive material 15,16, to can all be covered by sheet 15,16.Especially, because sheet 14,17 is only suitable for being out of shape by the bending in a direction only, so they do not contact placement with lug 8,9,10,20, to prevent their fractures during will being destructive bending.
The 4th step is, the second sheet of conductive material 16 is located, and to make above second of second sheet of conductive material 16 relative with the first surface of the second sheet of conductive material 16, stretches ferromagnetic material sheet 14,17.
Just now the method for having described is the method for an embodiment.In the case without departing from the scope of the present invention, those skilled in the art revises imagination its variety of way.Especially, when the latter preferably adopts single aluminium flake to make, those skilled in the art removable second and the 4th step.Those skilled in the art can put upside down step order, and wherein the first step in two steps can equality be carried out a step before another, or executed in parallel.Equally, by sheet 14 and 17 is positioned on sheet 16, then, by sheet 15 being positioned to obtain by this way stacking upper, the 4th step can be performed before third step.
In a word, in disclosed configuration, additional FINEMET sheet mainly reduces low cut-off frequency, and the thickness of aluminium increases decay.
